The night mode on Xiaomi smartphones is not just a fashion trend, but a useful feature that helps reduce eye strain in the evening and extend battery life. Many users do not even realize that their device supports two types of night mode: Classic blue light filter (reduces harmful radiation) and dark theme (reverses the color palette of the interface) and the settings of these functions are hidden in different sections. MIUI, which often causes confusion.
In this article, weβll look at all the ways Xiaomi can activate night mode, including hidden options for power users, how to set up automatic on schedule, which models support adaptive lighting adjustment, and why the feature sometimes fails to work, and a unique life hack for synchronizing night mode with the system clock for travelers, which is not in the official documentation.
What is Xiaomi Night Mode and Why You Need It
The night mode in Xiaomi smartphones combines two key functions:
- π Dark theme β completely repaints the interface MIUI darker tones, reducing screen brightness and reducing energy consumption (especially on the screen) AMOLED-display).
- π΅ Blue light filter β blocks part of the harmful spectrum that prevents you from falling asleep and causes eye fatigue.
Studies show that using a smartphone without a blue light filter 1-2 hours before bedtime can slow down the production of melatonin (the sleep hormone) by 55%, while a dark theme not only saves vision, but also prolongs autonomy by 5-15% by reducing screen load. AMOLED-Matrix (for example, Xiaomi 13 Pro or Redmi) K60) The effect is even more noticeable β black pixels simply turn off without consuming energy.
It is important to understand the difference between these modes:
| Function | Effect on the eyes | Battery savings | Supported models |
|---|---|---|---|
| Dark subject. | Reduces overall brightness | ++ (up to 15% AMOLED) | All of them MIUI 10+ |
| Blue light filter | Blocks the harmful spectrum | + (5%) | All of MIUI 9+ |
| Adaptive brightness + night-time | Maximum protection | +++ (20%) | Xiaomi 12/13/14, Redmi Note 11/12 |
Fun fact: on some flagships (for example, Xiaomi 13 Ultra) night mode automatically activates DC-Dimming is a technology that reduces the flickering of the screen at low brightness, and it's especially useful for people with hypersensitivity of the eyes.

How nighttime mode affects battery and performance
Studies show that a properly tuned night mode can extend autonomy by 5-20% depending on the model.
- π Nana AMOLED-In the case of the Xiaomi 13 Pro, the dark theme reduces power consumption by 10-15%, as the black pixels are completely turned off.
- π Blue light filter reduces the load on the GPU, which gives an additional 2-5% savings.
- β‘ On devices with LCD-displays (for example, Redmi 10) the effect is less - about 3-7%, since the backlight is constantly running.
But there's a downside: on some models, night mode can increase the workload on the processor due to additional color processing. POCO F3 With the blue light filter on and the dark theme on, the Snapseadragon 870 consumes 8 to 12 percent more power when scrolling through web pages, which is because the system has to redraw the interface.
To maximize battery savings:
- π Use only a dark theme without a blue light filter on the AMOLED-device.
- β±οΈ Set the schedule so that the night mode is turned on 1-2 hours before bedtime and turned off in the morning.
- π Track battery consumption in Settings β Battery β Battery usage β if you notice an abnormal flow rate, turn off adaptive functions.
